RE: [Serusers] Quick start SER Too much shared memory

Tks Andrei, I read this issue yesterday and tks for pointing this out. Sorry Im a bit of newbie to Linux so don't know which kernel version I have. Got a couple of other postings asking how I know which version of the kernel Im using. FYI I have Debian woody installed and Ive spent several hours yesterday looking through the documentation to try to find it. Maybe Im looking in the wrong place. I may just try the recompile of ser but then I need to work out how to do that too. Im enjoying this steep learning curve and it is steep.
